Die bekannten enzymatischen Entschlichtungsmittel enthalten neben Amylasen erhebliche Mengen an Kochsalz, die zur Vollaktivierung der Amylasen notwendig sind. Es ist weiter bekannt, den Entschlichtungsmitteln noch wasserlösliche Calciumsalze als Stabilisierungsmittel gegen Wärmeeinwirkung zuzusetzen. Als wasserlösliches Calciumsalz ist fast ausschließlich das Calciumformiat verwendet worden.The known enzymatic desizing agents contain not only amylases but also considerable amounts of table salt, which are necessary for the full activation of the amylases. It is further known water-soluble calcium salts as stabilizers against the desizing agents Add heat. Calcium formate is almost exclusively used as a water-soluble calcium salt been used.
Abgesehen davon, daß die leicht wasserlöslichen Calciumsalze wegen ihres hohen Preises nur in geringen Mengen von 2 bis 3% zugesetzt werden konnten, wirkten sie auch auf die Lagerfähigkeit der Fertigprodukte ungünstig ein.Apart from the fact that the easily water-soluble calcium salts are only available in If small amounts of 2 to 3% could be added, they also had an effect on the shelf life the finished products unfavorably.
Es wurde nun gefunden, daß optimale Aktivität und Stabilität der Entschlichtungsmittel nur dann erreicht wird, wenn neben erheblichen Mengen an Kochsalz ausreichende Mengen an Calciumsalzen vorhanden sind und daß man als Calciumsalz mit Vorteil Calciumsulfat, insbesondere Gips, verwenden kann. Es wurde weiter gefunden, daß ohne Beeinträchtigung der technischen Eigenschaften des Entschlichtungsmittels der Gehalt an Gips des Fertigproduktes so weit gesteigert werden kann,It has now been found that only then can the desizing agents achieve optimal activity and stability is achieved if, in addition to considerable amounts of table salt, sufficient amounts of calcium salts are present and that calcium sulfate, in particular gypsum, is advantageously used as the calcium salt can. It was also found that without impairing the technical properties of the desizing agent, the gypsum content of the finished product can be increased so much,
daß die gewünschten optimalen Wirkungen erreicht werden. Erfindungsgemäß wird vorgeschlagen, die Entschlichtungsmittel mit Calciumsulfat in großen Mengen, d. h. mehr als 6 bis zu 25 % des Gesamtgewichtes des Mittels zu -versetzen.that the desired optimal effects are achieved. According to the invention it is proposed that Calcium sulphate desizing agents in large quantities, d. H. more than 6 up to 25% of the total weight of the remedy.
Da die bekannten Verfahren zur Herstellung von Trocken-Amylasepräparaten zum überwiegenden Teil darauf beruhen, daß die Enzymträger, seien es Pankreasdrüsen, seien es Bakterien-Enzymkonzentrate, mit wasserfreien, aber mit viel Kristallwasser kristallisierenden Salzen, insbesondere Natriumsulfat, gemischt und anschließend getrocknet und vermählen werden, ist es bei Anwendung dieser Verfahren mit Schwierigkeiten verknüpft, neben der für die Aktivierung notwendigen Menge Kochsalz, die für die Temperaturstabilisierung erforderliche Menge an Calciumsulfat in das Fertigprodukt einzubringen, weil dieses durch erhebliche Mengen an Natriumsulfat, die nur als Ballast wirken, in Anspruch genommen ist.Since the known processes for the production of dry amylase preparations predominantly Partly based on the fact that the enzyme carriers, be it pancreatic glands, be it bacterial enzyme concentrates, with salts which are anhydrous but which crystallize with a lot of water of crystallization, in particular Sodium sulfate, mixed and then dried and ground, it is when applied this procedure is associated with difficulties, in addition to the one necessary for activation Amount of table salt, the amount of calcium sulfate required for temperature stabilization in the Bring finished product, because this is caused by significant amounts of sodium sulfate, which only as Ballast act, is used.
Erfindungsgemäß kann man die Nachteile des bekannten Verfahrens zur Herstellung vom Trockenprodukten dadurch vermeiden, daß man den Enzymträger mit Calciumsulfat, insbesondere mit Rohgips, vermischt und dieses Gemisch dann zur Trockene bringt und vermahlt. Es ist bereits bekannt, bei dem Trockenverfahren unter Verwendung von Natriumsulfat auch zusätzlich entwässertes Calciumsulfat zu verwenden, jedoch ist auch auf diese Weise keine Möglichkeit, ausreichende Mengen an Calciumsulfat in das Endprodukt einzubringen, weil der wesentlich größere Anteil an Verfestigungsmaterial immer das Natriumsulfat sein mußä das mit 10 Mol Wasser .35 kristallisiert, während der entwässerte Gips nur mit 2 Mol Wasser kristallisiert.·According to the invention, the disadvantages of the known process for the production of dry products can be avoided by mixing the enzyme carrier with calcium sulfate, in particular with raw gypsum, and then bringing this mixture to dryness and grinding it. It is already known to be used in the dry process using sodium sulfate in addition dehydrated calcium sulfate, but also contribute in this way, no way, sufficient amounts of calcium sulfate in the final product because of the much larger proportion of solidifying material must always be the sodium sulfate etc. that crystallizes with 10 moles of water .35, while the dehydrated gypsum crystallizes with only 2 moles of water.
Das neue Verfahren vereinigte daher die technisch sehr leichte Ausführbarkeit mit außerordentlicher Wirtschaftlichkeit, da der vorzugsweise verwendete Rohgips ein jederzeit verfügbares, sehr /billiges Rohmaterial darstellt.The new process therefore combined the technically very easy feasibility with the extraordinary Economy, since the preferably used raw plaster of paris is always available, very / represents cheap raw material.
Es ist bereits bekannt, Calciumsulfat einer MaIzamylase enthaltenden wäßrigen Stärkezubereitung bei der Verzuckerung zwecks Wärmestabilisierung zuzusetzen (USA.-Pätentschrift 905 029). Aus dieser der Brauereiindustrie entstammenden Erkenntnis war aber die vorteilhafte Wirkung des erheblichen Gipszusatzes zu Entschlichtungsmitteln nicht ohne weiteres herzuleiten. Diese besteht neben dem niedrigen Preis des Gipses auch darin, daß der hohe Gipsgehalt die Anwendung des Entschlichtungsmittels in einem Wasser niedrigen Härtegrades ohne weiteres ermöglicht.It is already known that calcium sulfate is a malamylase containing aqueous starch preparation in the saccharification for the purpose of heat stabilization to be added (U.S. Patent 905 029). From this knowledge stemming from the brewing industry but was the beneficial effect of the considerable addition of gypsum to desizing agents not to be deduced without further ado. In addition to the low price of the plaster, this also consists of that the high gypsum content lowers the use of the desizing agent in water Degree of hardness easily made possible.
300 g eines festen Bakterienamylasepräparates werden mit 200 g Calciumsulfat und 500 g Kochsalz vermischt,300 g of a solid bacterial amylase preparation are mixed with 200 g of calcium sulfate and 500 g of table salt mixed,
100 g eines flüssigen Konzentrats einer Bakterienamylase werden mit 280 g Calciumsulfat eventuell in Form von feingemahlenem Rohgips vermischt und das Gemisch dann in üblicher Weise vorsichtig getrocknet und vermählen. Das Produkt wird dann mit solchen Mengen an Kochsalz und weiteren Mengen an Gips vermischt, daß der Gipsgehalt der fertigen Mischung etwa 25% und der Kochsalzgehalt etwa 5Qfl/a betragen.100 g of a liquid concentrate of a bacterial amylase are mixed with 280 g of calcium sulfate, possibly in the form of finely ground raw gypsum, and the mixture is then carefully dried and ground in the usual way. The product is then mixed with such amounts of table salt and other amounts of gypsum that the gypsum content of the finished mixture is about 25% and the table salt content is about 5Q fl / a.
Getrocknetes, entfettetes Pankreatinpulver wird mit Calciumsulfat und Kochsalz derart vermischt, daß der Gehalt an Calciumsulfat etwa 25% und der Gehalt an Kochsalz mindestens 50 %> betragen.Dried, defatted pancreatin powder is mixed with calcium sulfate and table salt in such a way that that the content of calcium sulfate about 25% and the content of table salt at least 50%> be.
Ein aus Pankreasdrüsen in bekannter Weise hergestellter Drüsenbrei wird mit der dreifachen Menge feinen Rohgipses vermischt und das Gemisch dann in üblicher Weise vorsichtig getrocknet und vermählen. Das vermahlene Produkt wird dann mit solchen Mengen an Kochsalz und weiteren Mengen an Gips vermischt, daß der Gipsgehalt der fertigen Mischung etwa 25 % und der Kochsalzgehalt etwa 5% betragen.A glandular pulp made from pancreatic glands in a known manner is threefold Amount of fine raw gypsum mixed and the mixture then carefully dried and in the usual way to marry. The ground product is then mixed with such amounts of table salt and additional amounts mixed with gypsum that the gypsum content of the finished mixture is about 25% and the salt content about 5%.
